During uncoiling, the magnetic particle damping device delivers optimal tension to the paper. Featuring a paper receiving device, it allows the new paper roll to seamlessly adhere to the end of the previous roll without halting operations. A high-speed cutter efficiently trims the final segment of the prior roll, enabling continuous impregnation. Remarkably, this process requires only a single staff member for paper receiving.

Comprising a robust frame, aluminum roller, and advanced damping device, our innovative design also includes a paper receiving mechanism, two sets of dual-cylinder roller inflatable gas systems, along with two electronic magnetic powder brakes and a safety chuck for enhanced performance.

 

3.2 Impregnator (Initial Dipping Stage)

Our state-of-the-art impregnating machine is ingeniously assembled with a sturdy frame, a precision coating section, a comprehensive breathing system, an effective impregnating roll unit, a meticulous meter device, a versatile glue tank, and an efficient heating device for the glue tank.

This cutting-edge impregnating machine excels in the initial impregnating phase. Utilizing a coating roller for precise single downside coating, it ensures resin glue penetration from beneath the paper, efficiently expelling air from the top. The coating device is enhanced with a dynamic breathing system, tailored to accommodate varying paper types, resin glues, and impregnation techniques, allowing for precise breathing section height adjustments. This guarantees optimal glue absorption and paper flatness, as resin permeates the paper fabric, minimizing tensile strength loss and promoting seamless impregnation.

After passing through the coating and breathing sections, raw paper advances to the glue tank. The gap adjustment of the metering roll precisely regulates resin content and uniformity, achieving meticulous impregnating consistency, with motion accuracy of the metering roll maintained at ≤ 0.003mm.

Technical Configuration Requirements: Incorporates a sturdy frame, S roller, advanced back coating segment, efficient impregnating roller section, and precision metering roller. φ290, High-precision metering device, advanced breathing system, and a middle section crafted from stainless steel (430) glue tank with spacers. The glue tank's elevation is expertly managed by a worm gear reducer. The metering roller uses imported NSK bearings from Japan, ensuring the roller's wall thickness remains undeformed, complemented by dual motors for the breathing roller.

3.4 Roller Coater (Second Step Coating)

This innovative machine comprises a sturdy frame, upper and lower mesh-coated squeegee devices, and a sophisticated second smoothing device with lifting capabilities. The second overcoating machine ensures the paper's coating liquid achieves the required smoothness on the surface before applying the glue. By applying a secondary coating, the machine evenly covers the surface with glue, ensuring precision and quality. The choice of mesh size is crucial, as it directly influences secondary glue application. The process concludes with a finely polished finish, ensuring the tape's smoothness and uniformity as it enters the secondary oven.

Configuration Requirements: The upper and lower roller coating change speed frequency and converter speed are paramount. With a smooth roller equipped with a cylinder lift and frequency-controlled positive and negative adjustments, the high and low angle can be conveniently adjusted. The plastic tank, crafted from premium stainless steel (S430), and imported NSK roller bearings exemplify superior quality and durability.

Supply Range: Frame, Upper and Lower Coating Machine. The machine utilizes mesh coating technology.
